1.  “Hot Topics in Neonatology; December 12-14, 1993, Washington DC, USA” 
As a guest discussant, I had the pleasure and privilege of being invited to this important meeting which is held yearly. As the name implies, this meeting has its focus on subjects in which there was tremendous changes in the field of Neonatal Medicine, also on subjects where there is unanswered questions and controversial issues. The meeting was organized and chaired by Prof. J.F. Lucey, a well-known celebrity from the Pediatric World and the editor of the highly reputed journal, Pediatrics.

2.  The Symposium that I attended: “Hepatocellular carcinoma prevention” 
A symposium on liver disease was held in Jeddah on Dec. 1992. Hepatocellular carcinoma (HCC) which is prevalent in hepatitis B carriers, is one of the malignant tumours with the highest mortality.
A study conducted in Jeddah strongly supported the role, of hepatitis B and C in the development of liver carcinoma in Saudi Arabia.
Since HCC, is asymptomatic in its early stages, clinical presentation is usually late, when the tumour is inoperable. However, the successful resection rate of early tumours is high. Primary prevention, therefore, is the goal. This includes the screening for vaccination against hepatitis B and should in the near future be included in health education.
Early detection and diagnosis is possible through serology markers – serum–alfa–fetoprotein (AFP) and GTT–isoenzymes.
AFP is sensitive and inexpensive, and is suitable for HCC screening of hepatitis B carriers in whom its sudden rise is significant. Early diagnosis of HCC, at this stage, can be confirmed by sonography and CT scan.
It is recommended that serum AFP levels be used for screening hepatitis B carriers in hospitals and PHC centers, in Saudi Arabia.
